Features & Product Details

Just like other wear and tear items, your factory rear shifter bushing will become soft over time, creating a loose shifter feel and increased movement under all acceleration circumstances. The Kartboy unit eliminates this problem by tightening up any loose ends with their much stiffer design.

These are hand-made here in the U.S.A., and are made using the finest urethane materials to provide years of performance.

Please note that this bushing may raise the shifter height when used on 1998-2005 Forester, 2000-2004 Legacy, 2003-2006 Baja, and 1998-1999 Legacy Outback models.

Quality product, but not the easiest install 8 months agoWonderbrett
I went on Nasioc and also watched a few videos on install as I’d never done it before and it looked like a pretty straight forward install and wouldn’t take me too long. There isn’t much room for install so I ended up removing the 6 bolts for the cross member to have a little extra space. I have smaller hands and was able to work around my DP, but I might recommend removing it for a little more ease of access. When installing the rear bushing I left the front one out as I did both at the same time, but I put the washer and nut on the front shifter link to keep it from moving around too much when trying to line up the rear bushing. This is where I ran into some trouble. I was only able to get one bolt in, until I grabbed a pry bar and pushed on the bushing to align up with the second bolt hole. Overall with my usual slow self it took me about 2 hours total in my driveway. As popular of a company as Kartboy is I was kind of disappointed with how the bushing doesn’t quite line up enough for ease of installation, but after install on my first shift I felt a drastic difference. Shifts are much crisper and I can feel my shifts as I’m making them. Overall would buy it again and I’m only knocking off 1 star due to installation.

Don't expect too much. 3 years agonickch
A lot of instructions and forum posts say that the rear shifter bushing was difficult to install.
It took me about 1.5 hours, extremely taking my time as I was giving the drivetrain a good inspection.
So it wasn't really too difficult but it wasn't easy either.
There isn't much room to play around with, so having the right tools really come in handy.
A few tips on a 2002 WRX:
- Leave the stock bushing bolted (after cracking them loose) while you free up the front shifter bushings. This makes it easier to pop out of the rear bushing.
- Pop the end into the rear bushing first, before starting to thread the bolts in.
- I found using 1/2 drive rachet/socket with a few extensions made doing the bolts up a whole lot easier. But make sure you don't over torque the bolts potentially stripping the threads.
Shifter Feel:
I already had pivot bushings and the front bushings installed for several years now. I bought this with the intent of completing the ensemble. To be honest, there wasn't that much difference in feel. The pivot bushings and front shifter bushings are probably the ones making the most difference.
That being said, when comparing the stock rear bushing with the kartboy one, especially when the stock one has been on the car for > 15 years, it is definitely a good replacement, and the Kartboy ones are very solidly built.

Hard for me to differentiate which product did what, But MAN, I can tell the difference, With a 2011 Fully built WRX (EJ257 block, 380HP) and no suspension upgrades, These products were amazing.
PROS
- Rear end is muuuch tighter/sticks to the road during turns and taking off from stop
- Acceleration is improved greatly, and feels like you have more power
- Feels like power is going into the ground more
- Very little drive line shock
- Shifting is solid
- went from feeling like a semi truck, to a Indy Super Race car
CONS
The rear shiftier bushing, was hard to line up with the existing holes (turn a little by little on each side)

Manufacturing flaw? 3 years agoSouper Roo
Got this bushing as a gift from my lady this Christmas. When inspecting the product it looked perfect. I planned to have an install time of about an hour on my 2006 Impreza WRX. That was not the case. When I was about to bolt it down i got one bolt in and not the other. After I cleared my mind of anger and frustration i wised up and used a pry bar in between the driveshaft and shifter linkage to stretch the bushing which allowed me to get the last bolt in. I would recommend doing the same if you find yourself in the same situation. The only difference I have noticed is that when i let off the gas my gear knob doesn't shift forward the tiny bit it used to. I have attached a picture that i took with my borescope of the distance i needed to stretch the bushing.

What is the rating of durometer polyurethane bushing used?
Please post it in the description as Kartboy's website does not have this info as well. Very important people for users to understand, thanks!
